master cylinder

can you get the piston out of the master cylinder on a 1984 750 and if so how?

 

After you take off the rubber dust seal, remove the circlip.

 

r u talking about the one behind the brake lever?

 

Yes. You have to remove the brake lever to acces the dust seal. To get the circlip out you'll need a long nose reach circlip pliers.

 

once i do that where would i find a rebuild kit for it.

 

Here's a link to Chacal's parts catalog:

You'll find what you need there including special pliers to get out the circlip.

 

that link helped alot. thanx

 

got the master cylender done now any secrets to geting the brakes off the disk. they are not froze up the wheel turns itook the bolt off the top but cant get it to break loose.

 

If I've read this right, your discs may be worn and have a "lip" on the edge that hinders removing the caliper. Try "twisting" the caliper on the disc to push the pads apart.

You have removed both caliper mounting bolts, right?

 

yes twisting it got it off. now the how dow i get the caliper apart its froze up and wont engage ive tried using air to pop it out but the bike sat for 16 yrs in a field. do i try to rebuld this one our is it better to try and find a used one that works.

 

Just crack the bleeder valve open a bit, and attach a grease gun to it. Block off the banjo hole... It takes just a few pumps and the piston is out. Just make sure you clean the grease up really good. Also, take the rubber o-rings out of the master cylinder and scrape all the crud out from the grooves.

 

which caliper are you working on?
The 650 or 750?

 

the 750
